ォーク。The inner and outer cylinders are slidably fitted together, a seat pipe is installed in the inner bottom of the outer cylinder, and an oil hole is drilled in the side wall of the outer cylinder to communicate the oil passages inside and outside the seat pipe. The oil hole is closed by a piston having a U-shaped cross section, and an annular groove is formed in the surface of the side wall of the outer cylinder in which the oil hole is bored, which faces the piston, and the inner diameter of the groove is approximately the same as the oil passage diameter. - In an anti-dive front foo formed by press-fitting an annular packing, an annular seal portion with the same diameter as the inner diameter of the annular packing is protruded from the surface of the outer cylinder wall side of the annular packing, and a plurality of notched grooves are formed on the outer periphery. Anti-dive front fork.
